If `y=sin^(-1)((2x)/(1+x^2))` , write the value of `(dy)/(dx)` for `x >1` .

y=sin^(-1)((2x)/(1+x^(2))), prove that (1+x^(2))(dy)/(dx)=2

If y=tan^(-1)sqrt((1-sin x)/(1+sin x)), then the value of (dy)/(dx) at x=(pi)/(6) is.

if y=cot^(-1)(sqrt((1-sin x)/(1+sin x))) find the value of (dy)/(dx)

If y=sin^(-1)(sin x),-(pi)/(2)<=x<=(pi)/(2). Then, write the value of (dy)/(dx) for x in(-(pi)/(2),(pi)/(2))
